AIM To observe the combinative therapeutic effects of Mailuo Shutong Granules and routine synthetic medications on patients with superficial thrombophlebitis (STP).METHODS Seventy patients randomly and equally divided into control group and observation group were subjected to a two-week conventional treatment and a two-week intervention of Mailuo Shutong Granules on the basis of routine treatment,respectively,and they had the before and after the treatment assessment in terms of main clinical symptoms and signs,endothelial function indices (NO,ET-1,TXB2,6-Keto-PGF1α,VEGF,vWF),hemorheology indices (plasma viscosity,blood sedimentation,erythrocyte aggregation index,fibrous protein).RESULTS The observation group generally demonstrated significantly higher effective rate than the control group (P ＜ 0.05).Markedly decreased post-treatment scores for main clinical symptoms and signs,TXB2,ET-1,vWF,plasma viscosity,blood sedimentation,erythrocyte aggregation index,fibrous protein,and increased 6-Keto-PGF1 α,VEGF and NO (P ＜ 0.05) in both groups were observed,as well as the between-group variance showing the observation group's priority (P ＜ 0.05).The respective 8.57％ and 14.29％ incidence rates of adverse reactions in the observation group and control group were also noticed.CONCLUSION For patients with STP,a combination therapy of Mailuo Shutong Granules on the basis of synthetic medications contributes to an effective main clinical symptoms alleviation due to its vascular endothelial cells protection,cellular secretion function and hemorheological improvement.

OBJECTIVETo observe the differential effect of joint ultrasound on the syndrome differentiation of rheumatoid arthritis (RA) by observing the high frequency ultrasound performances among inactive stage and different syndromes in active stage.

METHODSTotally 83 RA patients in the active stage were assigned to the dampness heat syndrome group (DHS, 59 cases)and the cold dampness syndrome group (CDS, 24 cases) according to Chinese medicine (CM) syndrome typing. Besides, 20 RA patients in the remission stage were recruited as the control group (abbreviated as the remission group). By using high frequency ultrasound and power Doppler ultrasound technology, a comparative observation of synovitis, tenosynovitis, synovial blood flow, and bone erosion in the 2nd-5th metacarpophalangeal (MCP) joints, proximal interphalangeal (PIP) joints, wrist joints, knee joints, the second and the fifth metatarsophalangeal (MTP) joints (a total of 24 joints) was performed in all patients. Correlation analyses were performed between the ultrasound performance, laboratory indices, and the disease activity. Ultrasound data of each RA patient were analyzed by their total scores. Χ2 test was used for enumeration data. The measurement data was expressed as x ± s. One-way ANOVA was used for data of normal distribution, while non- parametric test was used for data of non-normal distribution. Correlation analysis of two variables was performed for clinical indicators and ultrasound indicators. Its significance was detected using Pearson correlation.

RESULTSCompared with the remission group, the severity degree of synovitis, tenosynovitis, synovial blood flow, and bone erosion significantly increased in the DHS group (P < 0.01). There was statistical difference in ESR, CRP, anti-CCP, DAS28 score, and the positive rate of RF (P < 0.05, P < 0.01). There was statistical difference in the severity degree of synovitis and synovial blood flow, and DAS28 score in the CDS group (P < 0.05). Compared with the CDS group, there was statistical difference in the four ultrasound indices (P < 0.05, P < 0.01), ESR, CRP, anti-CCP, DAS28 score, and the positive rate of RF in the DHS group (P < 0.05, P < 0.01). There was no statistical difference in G, IgG, IgA, or IgM among the three groups (P > 0.05). There existed positive correlation between ESR and the synovitis degree, synovial blood flow, and bone erosion in the DHS group (r = 0.444, 0.397, 0.486, P < 0.05).There existed positive correlation between ESR and the synovitis degree, bone erosion, and synovial blood flow in the DHS group (r = 0.378, 0.270, P < 0.05). There existed positive correlation between the DAS28 score and the synovitis degree and synovial blood flow in the DHS group (r = 0.304, 0.351, P < 0.05).

CONCLUSIONSThe inflammation degree was the most severe in RA patients of DHS. High frequency ultrasound could provide better evidence for Chinese medical syndrome differentiation of RA patients.

OBJECTIVETo determine the optimum treatment for viral myocarditis (VMC).

METHODSA total of 126 VMC patients were randomly divided into the control group (42 cases) that was treated with conventional Western medicine, and the intervention group (84 cases) that was treated with a combination of Chinese medicine (CM) and Western medicine intervention termed optimum proposal of integration of disease and syndrome (OPIDS). Before and after 4 weeks of treatment, the integral of CM syndrome, self-rating depression and anxiety scales (SDS and SAS, respectively), echocardiograms (ECGs), heart rate variability and left ventricular systolic function were observed.

RESULTSCompared with the control group, the intervention group showed significant reductions on the SDS and SAS (P <0.05); improvement of premature ventricular beats, atrioventricular blocks, ST-segment abnormalities, and significant T wave changes (P <0.05); greater reductions in standard deviation of NN intervals (SDNN), standard deviation for per 5 min averages NN intervals (SDANN), and root-mean-square of successive difference of NN intervals (rMSSD) (P <0.05); and increases in cardiac output, stroke volume, and ejection fraction, the last of which was statistically significant (P <0.05). Overall, the treatment efficacy rate was significantly better P<0.05) in the intervention group (75.61%) compared with the control group (69.70%).

CONCLUSIONOPIDS is quite effective in treating VMC and improves symptoms such as anxiety and depression, left ventricular systolic dysfunction, premature ventricular contraction, and cardiac autonomic nervous system dysfunction. [

The microbial transformation of buflomedil by Cunninghamella blakesleana AS 3.153 was studied, as well as a microbial model which can be used to mimic metabolism of buflomedil in mammal was established. Experiments were conducted to screen the capabilities of four strains of Cunninghamella species to transform buflomedil, in which C. blakesleana AS 3.153 was selected for a preparative biotransformation. Furthermore, the microbial model was established based on the transformation condition optimization. The parent drug and its metabolites produced by C. blakesleana AS 3.153 were detected by liquid chromatography-mass spectrometry method and three metabolites were identified while two of them were new found metabolites. Two major metabolites, para-O-desmethyl buflomedil and 12-C-oxidated buflomedil, were isolated by semi-preparative HPLC. Based on the comparison between different species, the microbial transformation of buflomedil by C. blakesleana AS 3.153 is more similar to the metabolism of buflomedil in human and Beagle dog than that in rat.

This article studies the thermostability and the crystal structure of a new anticancer drug dasatinib. The thermostability of dasatinib was analyzed using the differential scanning calorimeter (DSC) and thermo gravimetric analyzer (TGA), and the structural characteristics of polymorphism and crystalline transformation was determined using the X-ray powder diffractometry (XRD) with in-situ high temperature accessories. The results showed that dasatinib has at least two different crystal forms. The form-I has one crystalline water and form-II one and half, and in a heating-up processing both of them would change their crystal structures. After losing their crystalline water, both would change into the same crystalline form with no crystalline water. Their melting points were almost the same: form-I was 285.68 degrees C and form-II was 285.50 degrees C. The results of the study method would provide a comprehensive reference for the quality evaluation of dasatinib.
